An antorbital fenestra (plural: fenestrae) is an opening in the skull that is in front of the eye sockets. This skull character is largely associated with...

Morrison Formation, as suggested by such attributes as still having antorbital fenestrae in the skull. The limbs were relatively long, suggesting that the...

and other more primitive pterosaurs which had separate nasal and antorbital fenestrae. However, according to Wang e.a. it is equally possible that the...

of fenestrae (skull openings) in its skull, two pairs of which were for the eyes and nostrils. Between the eyes and the nostrils were two antorbital fenestrae...

skeletal remains and the eye was mistakenly placed in one of the antorbital fenestrae),[citation needed][original research?] as well as ultimately and...

crests also had air sacs (a ridge of bone forms a roof over the antorbital fenestrae in most other theropods). The orbit was oval, and narrow towards...

Irritator shared with crocodilians a stiff secondary palate and reduced antorbital fenestrae. In 2007, a finite-element analysis study by British paleontologist...

consisting of nodular protuberances on the skull, antorbital fenestrae facing dorsally, and a restricted antorbital fossa on the maxilla. The genus comprises...

maxillary and promaxillary fenestrae), and a narrow interfenestral strut (the bar of bone between the maxillary and antorbital fenestrae). Geminiraptor is uniquely...

theropods, various fenestrae (openings) in the skull aided in reducing its weight. In spinosaurs however, the antorbital fenestrae were greatly reduced...

most obvious features include teeth set in deep sockets, antorbital and mandibular fenestrae (openings in front of the eyes and in the jaw, respectively)...

cavities or sinuses. In zoology, there are openings in the skull called fenestrae. The human skull is the bone structure that forms the head in the human...

narrow and horizontally positioned; the same was true of the larger antorbital fenestrae, a pair of bony openings in front of the eyes. The rear of the skull...

archosaurs from other diapsids is an extra pair of openings in the skull (antorbital fenestrae) in front of the eye sockets. Archosauria is the crown group containing...

external nares (nostril holes) are elongated, much larger than the antorbital fenestrae (a hole on the side of the skull). Many aetosaurs have a small knob...

The phytosaur by the marginal overlapping of the nostrils by the antorbital fenestrae, external nares based on a bulbous and raised dome, the lateral surface...

maxilla at the tip of the snout, and the reduction or absence of the antorbital fenestrae (a pair of holes in the snout in front of each orbit). A close relationship...
